LOCK.

SPECIFICATION forming part of Letters Patent No. 545,418, dated August27', 1895.

Application filed October 29, 1894. Serial No. 527,243. (No model.)

.b all whom it may concern.:

Be it known that I, FRANK SOLEY, a citizen of the United States, and aresident ot Philadelphia, (Frankford,) in the county of Philadelphia andState of Pennsylvania, have inventcd certain new and useful Improvements1n Locks, of which the following is a specification.

My invention relates to cylinder-locks applicable to all purposes, suchas latch-locks, dead-locks, drawer-locks, truuklocks, and lock-boxes.The object of my invention is to generally improve the construction ofcylinder and latch locks, and in orderto enable others skilled in theart to which my said invention appertains to understand and use the sameI will proceed te describe the details-of its construction, explain itsoperation, and point out in the appended claims its novelcharacteristics.

Referring to the accompanying drawings, in which similar characters ofreference indicate corresponding parts throughout the several views,Figure 1 is an elevation at the back of a latch-lock, showing the end ofa cylinder made according to my invention, which is intended to projectthrough the door in the manner usual. Fig. 2 is a similar view with thecover and cylinder removed. Fig. 3 is a horizontal section on the line.sa ar, Fig. 1. 4 is an elevation at the back with the cover andlatch-bolt removed, showing the throw-o device. Figs. 4ta and 4h aredetached perspective views of the parts of the throw-oit device. Fig. 5is an inside end View of the cylinder, showing my improved manner ofattaching the roll-back to the cylinder. Fig. 6, which, together withthe remaining views, is enlarged, shows the outside end view of thecylinder removed from the shell. Fig. 7 is a cross-section on the line yy, Figs. l0, 12, and 13. Fig. 8 is a cross-section at .c .e in Fig. 9.Fig. 9 is an inverted plan view of the cylinder. Fig. 10 is a side viewof the cylinder. Fig. 11 is a horizontal section of the cylinder in theplane as az', Fig. 10. Fig. 12 is a side view, partly in section, of thecylinder and shell, the dog being removed and showing a special keyinserted. Fig. 13 is a similar view showing the master-key inserted.

Fig. 14 is a horizontal section of the cylinder, taken similarly as inFig. 1l, showing a modiiication of the dog.

Referring to Figs. 1 to 5, inclusive, the lock s frame or housing A isconstructed with the usual removable 'cover I3, bearing thecylinder-shell C, containing the cylinder` D. The latch-bolt E isactuated bythe roll-back 2, which is attached to the inner end of thecylinder D by the upset tenen 3, entering the mortise ofthe roll-back,attordinga stron g and cheap construction. The latch-bolt E isreversible, so as to strike either way, to adapt it to a door openingoutward or inward, the bevel 4e being placed as desired when the lock isput together. the bolt E has its shank 5 central, as seen in Fig. 3, andits spring 12 axial to the bolt snpported on stops 13 l1, and its twosides are symmetrical, and double sets of lugs 6 6 7 are provided forthe roll-back to engage with. The throw-ott handle F has its shank 8movable in the length oi' the slot 9 and inserted into the bolt-shank 5,as indicated in Figs. 2, 3, and 4. A squared part 10 of the shank 8carries the holdback 11, being upset over its squared hole, Figs. la and4b, and said holdback is composed of a spring bearing frictionallyagainst the inside of the housing A and catching in a recess 15 thereinwhen turned to the position indicated by dotted lines in Fig. 4,engaging with the stopA 16 after the bolt E has been thrown back anditis desired to prevent locking.

p Referring to Figs. 6 to 13, inclusive, the cylinder D is mortised at20 to receive the tumblers 2l and dog 22, and the keyhole 23 in the cap24 is formed at right angles to the tumblers, so that the notches 25 inthe end of the key shall determine the position of the tumblers. Thetumblers 2l are pivoted on the pin 26 and each is provided with aspring27, thus holding the group outwardly against the cap 24, and when thekey 28 or 29 is inserted its inward movement is limited by stops 30abutting on the cylinder D. Mortises 31 are cut into the sides of themcrtise 2O to receive and guide the key by means of its fork 32. Theshell C has a flange overlapping the cylinder D, and the aperture 34,Fig. 1, is of less diameter than the span ot' To afford thereversibility ZOO the stops 30 of the key. The key is inserted, itsstops 30 passing through the notches 35, Fig. 1, in the flange 33, andthen being turned the stops 30 pass behind the flange 33, which entersthe notches 36 behind the stops, retaining the key against thespringtumblers. rlhe tumblers may be provided with one or more sets ofnotches, as desired. Two are illustrated, one set being aligned in Fig.12 with a special key 28 and another set being aligned in Fig. 13 by themaster-key 29. The dog 22, pivoted at 40, is pressed with moderatetendency toward the tumblers by a spring 41, sufficient only to push thespur 42 into the notches of the tumblers when aligned. The dog engageswith the mortise 43 in the shell C to lock the cylinder D. The movementof the dog 22 whereby it engages and disengages with the shell C isindependent of the rotary movement of the cylinder, and for this purposeI provide square shoulders 44 44 upon the sides of the dog 22 andcorresponding shoulders or sides in the morlise 43. A rotating forceapplied to the cylinder D can thus have no effect upon the pressure ofthe dog 22 against the tumblers 2l.

In Fig. 14 the modication consists in utilizing the springs 27 for boththe tumblers 2l and the dog 22 by providing the latter With a spur 50,against which the springs all bear. A filling 5l is also shown in Fig.14 to intercept external access to the dog 22.

In Figs. 7 to 14, inclusive, the tumblers 2l are shown in the form ofsegments, which are advantageous in point of simplicity and cheapness ofconstruction and convenience of setting up.

The cylinder D is kept in place by means of a groove 65, extendingpartly around its circumference, and a stud-screw 66, inserted throughthe shell Cinto said groove, which is advantageous over formerconstructions having a slot in the shell and a screw-stud in the movablecylinder, which is liable to work loose.

IIaving thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a cylinder lock, the combination of a rotary cylinder, a shell, amortise in the shell,y

segmental tumblers pivoted in the cylinder, a locking dog pivoted in thecylinder beyond the arc of said tumblers engaging with said tumblers andcontrolled thereby to enter or withdraw from the said mortise, and meansindependent of the rotation of the cylinder tending to move the dog outof said mortise toward the tumblers.

2. In ay cylinder lock, the combination of a rotary cylinder, a shell, amortise in the shell, segmental tumblers pivoted in the cylinder, a dogin the cylinder pivoted beyond the arc of said tumblers and controlledthereby to enter or withdraw from the said mortise, and

`a spring tending to move the dog out of said mortise toward thetumblers.

3. In a cylinder lock, the combination of a cylinder, a shell, a dog inthe cylinder adapted to lock with the shell, a series of tumblerspivoted in the cylinder and formed in true segments with their arcscontaining notches located in the arcs of the segments and engaging withthe dog.

4. In a cylinder lock, the combination of a cylinder, a shell, a dog inthe cylinder' adapted to lock with the shell, a series of tumblerspivoted in the cylinder and formed segmentally with their arcscontaining notches variably located and engaging with the dog; said dog`being also pivoted in the cylinder and having a spur engaging with theseveral notched arcs of the tumblers.

5. In a latch lock, the combination with a suitable housing, and a latchbolt, of a throwV off device consisting in a suitable external handleand 'its shank connected with the bolt, and rotating on an axis at rightangles to the length of the bolt, and movable with the bolt in thedirection of the length thereof, and a segmental spring plate bearingfrictionally on the housing, connected rigidly to the shank of the saidhandle so as to rotate therewith, and a suitable stop in the housingwith which the plate is adapted to engage by rotation when the bolt hasbeen drawn back by the handle, and the latter partly rotated to throwoft the latch.

6. The rotary cylinderl provided with the retaining groove 65, therein,and the fixed shell provided with the retaining stud 66 for limiting therotary movement of the cylinder, substantially as shown.

7. In combination, a cylinder' having a mortise, a pack of tumblerspivoted in said mortise and disposed in parallel lines with thecylinder, mortises, as 3l, formed in the sides of the cylinder mortiseto receive and guide the key, and a key having a fork adapted to entermortises 3l, substantially as described.
